- 1- aspirin
- 2- NSAIDs
- 3- B blockers
- 4- Benzalkonium Cl
- 5 - Sulfite preservatives
Tidal Volume (what is it and how much)
- normal breathing
- 500mL
Inspiratory reserve volume (IRV)
(what is it and how much)
- max amt of air that can be inspired above TV
- max contraction of inspiratory muscles
- 2100-3200mL
Expiratory reserve volume (ERV)
(what is it and how much)
- extra amt of volume that can be expired after TV.
- about 100mL (600 when combined with TV)
Residual Volume (RV)
(what is it and how much)
- vol of air remaining after max expiration.
- 1200mL
Ispiratory Capacity(IC)
- max volume that can be inspired after TV
- TV+IRV=IC (approx 3500)
Functional residual capacity(FRC)
- vol in lungs after TV
- ERV+RV=FRC
Forced Vital Capacity (FVC, VC)
- max vol of air that can be moved out during a single breath following max inspiration
- IRV+TV+ERV=VC
Total lung capacity(TLC)
- max air in lungs
- VC+RV=TLC
alveolar ventilation rate (AVR)

vol of air exchanged betw the atmosphere and the alveoli per min

AVR(ml/min) = fq (breaths/min) x (TV-dead space)(ml/breath)
